Study 123 irregularity

Study #123 has multiple slices in its SAX directories. It is mentioned in Fourier Based Tutorial: Some datasets (e.g. #123) contain in their SAX folders not only the short axis stack images, but a number of other views of the heart presented in sync. This presents a problem to Dataset, which expects there to be only one slice in any folder. I can see multiple slices, but I went through all #123 SAX directories and I haven’t noticed different views. Am I mistaken?
